To a, whom it nuty concern.-

Be it known that I, OoNsTAN'rIN WAGNER, a citizen of the United States,residing at New York, in the county of Westchester and State of NewYork, have invented certain new and useful Improvements in TestingDevices; and I do hereby declare the following to be a full, clear, andexact description of the .invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates-to improvements in testing devices, and has forits object the pro vision of means for facilitating the testing of dairyproducts-as, for instance, butter.

With this and other objects in view the invention consists of certainnovel constructions, combnations, and arrangements of parts, as will behereinafter fully described and claimed.

In the drawing the figure is a perspective View of a device constructedin accordance with the present invention.

Referring to the drawing by numerals, 1 designates the body of a bottle,and 2 the graduated neck thereof. Intermediate the ends of the neck 2,and preferably near the lower portion thereof, a bulb 3 is formed. If itis desirable, a stopper may be placed in the neck 2, as is shown bydotted lines 4.

A funnel 5 is positioned contiguous to the body 1 and is integrallyconnected to the body 1 by means of a long stem 6, which stem is bentintermediate its ends, as at 7.

The lower end of the bent portion 8 terminates near the middle of andwithin the body 1. The long funnel 5 diverges at its upper end 9. Thefunnel 5 and a portion of the stem 6 not within the body are positionedparallel to the neck 2.

If it is desired to test butter, a standard amount of butter is insertedand weighed in the bottle at the normal temperature. After the exactamount of butter to be tested has been weighed and determined the bottleis warmed, so that the butter will run from the funnel into the bottle.Then a standard amount of acid is mixed with the butter and thiscomposition is rotated in any suitable regulation centrifugal machine.After this hot water is added, so that the bottom of the fat-column willbe level with the point marked A.

Among the advantages of this device one is that by means of the longstem and funnel water may be added to thecolumn of liquid. at will, soas to raise the column of fat, giving to the bottle all the advantagesof a U-shaped tube. Further, by gently pressing down or gently drawingup the rubber'stopper at the top of the graduated neck the fat may bemoved in the graduated neck, so as to bring the lower end of thefat-column level with a predetermined mark-as, for instance, A. When thecolumn of butterfat is exactly at A, the result may then be read uponthe graduated scale of neck 2. By employing the elongated funnel 5 andneck 6 liquid may be added or taken away from the bottle withoutdisturbing the butter-fat, whereas without this peculiar structure ofthe device it is impossible to remove any liquid from the bottle withoutat the same time removing some of the butter-fat.

It will be obvious that the device is formed of transparent material,preferably glass.

What I claim is 1. As a new article of manufacture, a test ing devicecomprising a bottle, said bottle provided with a body and a long neck, abulged portion formed in said neck intermediate its ends, an elongatedfunnel provided with a long stem, the stem integral with the body ofsaid bottle, and said stem bent intermediate its ends, the lower portionof said stem positioned within the body of the bottle and the funnel anda portion of the stem positioned parallel with the neck of the bottle.

2. In a testing device, the combination with a bottle provided with an.elongated neck, of a funnel positioned contiguous to said neck, a stembent intermediate its ends and integral with said funnel, the lowerportion of said stem positioned within and at an angle to thelongitudinal axis of said body.

3. The combination with a bottle having graduations formed thereon, of alongstemmed funnel integral with said bottle, and arranged parallel withsaid bottle, the lower portion of said stem be ng positioned within saidbottle at an angle to said bottle.

4. The combination with a bottle, of an elongated, long-stemmed funnelintegral In testimony whereof I aflix my signature with said bottle andparallel thereto, said in presence of two Witnesses.
